Figure 3 is a top plan view of the heel and its plate.

Figure 4 is a cross sectional view on the line 4-4 of Figure 3.

Figure 5 is a longitudinal sectional view taken substantially on theline 55 of Figure 6.

Figure 6 is a bottom plan view showing the seat heel plate and heelplate in connected relation.

Figure '7 is a sectional view taken substantially on the line 'I--I ofFigure 6.

Figure 8 is a section taken substantially on the line 8--8 of Figure 6.

Figure 12 is a plan view of the seat heel attached plate.

Figure 13 is a section on the line I3l3 of Figure 12.

Figure 14 is a section on the line I l-44 of Figure 12.

Referring to the drawings wherein lik numerals designate like parts, itcan be seen that the structure represented in the drawings consists offour main parts, namely, the shoe proper 5, a detachable heel 6, a plateI carried by the heel 6 and a plate 8 carried by the seat heel 9 of theshoe 5.

The heel may be leather. rubber or any other material and has itsforward edge portion stepped off as at ID to accommodate the shoe soleII. The plate I coincides with the configuration of the heel 6 and issecured upon the heel 6 by nails or the lik I2. It being preferable thatthe top of the heel have a basin therein upon the bottom of which theplate 1 is disposed and secured so that this plate Will not be visiblefrom the side of the shoe. This is also true of the plate 8 which issecured to the seat heel 9 of the shaped opening I4 at its intermediateportion.

As shown in Figure 4, the heel 6 just below the slot IS in the plate 'Iis formed with channels I5, while just below the rectangular-shapedopening I4 in the plate 1, a pocket It is formedin the heel B.

The seat heel plate 8 coincides with the-configuration of the plate Iand has a pair of parallel disposed struck-out L-shaped members I! whichride in the slots I3 and grooves I5 and also a struck-out tongue I8having an upwardly curved lip I9. This plate 8 also has a downwardlystruck-out cleat 20. The plate 8 is secured to the seat heel by sewingor tacking.

As is suggested in Figure 1, by registering the slot I3 with the memberI1 of the plate 8, the heel 6' can be slid into position with the cleat2|] and the spring tongue, I8 in substantial abutting relation with theends of the pocket I4.

The heel 6 is formed with a vertically disposed opening 22 through whichan elongated nail or other implement can be disposed in orderto flex thetongue I8 and dislodge the same from the pocket I6 and opening I4, tothe end that the heel 6 can be slid off of the plate 8 conveniently.While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is: In a shoeconstruction, a seat heel, a heel, a plate secured to the heel, saidplate being formed with a pair of spaced guide slots extending inwardlyfrom the inneredge thereof, said plate having a substantiallyrectangular opening, said heel being formed with recesses over whichportions of the plate at the slots and opening overhang, a second plateattached to the seat heel, said second plate being provided with a pairof L-shaped members extending inwardly from the inner edge thereof andadapted to be received by certain of the recesses and the slots, saidsecond plate being struck out to provide a spring tongue for dispositionthrough the opening of the first plate and into the corresponding recessand a cleat depending from the second plate and adapted to engage underthe first plate at the rear edge of the opening therein when the platesare in connected relation.
